Problem with restart

[Mike McClure]

What those errors mean is that the "su" in the script isn't working properly.  It
looks like the home directory for the "nagios" user is invalid or missing, or the
user is locked out or disabled.

Do you get the same errors from "/etc/rc.d/init.d/nagios start"?

Try taking out the "-l" in the line:

su -l $Nagios -c "touch $NagiosVar/nagios.log $NagiosSav"

That will keep su from doing a full login.  That might get rid of the error messages
without affecting the function of the script.

The errors are not fatal, like you said, it restarts anyway.  All it's doing is
making sure that a couple of files exist before Nagios starts up.  I don't think
it's absolutely necessary to have those files anyway, is it?  Someone please correct
me if I'm wrong.

An alternative to the "su" might be this:

---
# Flavor NagiosGrp to taste
NagiosGrp=nagios
touch $NagiosVar/nagios.log $NagiosSav
chown $Nagios:$NagiosGrp $NagiosVar/nagios.log $NagiosSav
chmod 640 $NagiosVar/nagios.log $NagiosSav
